Explanation:A special case of polar forces occurs in what is called the hydrogen bond. In many situations, when hydrogen forms a covalent bond with another atom , electrons move toward that atom, and the hydrogen acquires a slight positive charge. The hydrogen, in turn, attracts another atom, thereby forming a kind of bridge between the two.

The endometrium is the inner lining of the uterus. During the ovulation period, this wall thickens as it prepares the uterus for the eventual fertilization of an egg cell. It is composed of a basal layer and a functional layer, in which the latter sloughs off/sheds off during menstruation.
Therefore, it is the ENDOMETRIUM layer <span>of the uterus undergoes dramatic changes in thickness and structure during the uterine cycle responding to hormones.</span>
Answer;
-Protein ions
A resting axon's fluid interior has a mostly negative charge thanks to the presence of large protein ions.
Explanation;
-Intracellular and extracellular fluid of neurons contain various kinds of charged ions. These include sodium (Na+), potassium (K+), and chloride (Cl-). Additionally, these fluids contain many negatively charged protein molecules called anions (A-).
-The movement of such ions across neural membranes creates electrical activity. As ions move in and out of the cell, they bring their respective charges (either positive or negative) with them, thus influencing the voltage of cellular membranes.
-The protein molecules are large negatively charged proteins (anions) that are manufactured inside cells. They always remain inside the cell, as there are not membrane channels through which they can leave.Their charge contributes to the negative charge on the intracellular side of the membrane.

Explanation:
Limiting factors include a low food supply and lack of space. Limiting factors can lower birth rates, increase death rates, or lead to emigration. Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off.
